Robust Power Design

Stable power is crucial for maximizing the performance of Intel Core Ultra Processors (Series 2). The PRIME B860M-A is designed to meet the needs of high-core-count CPUs. It features 7(80A) + 1(80A) + 1(80A) + 1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80 amperes each. This configuration ensures optimal power delivery, efficiency, stability and performance for both current and future Intel® processors.

Six-Layer PCB Design
The multi-layered printed circuit board design quickly dissipates heat around the voltage regulators to improve overall system stability and provide the CPU with more overclocking headroom.

ProCool Connector
Proprietary connectors augment the motherboard’s link to the power supply with 8 pin connector that pass 12 volts of power directly to the processor. Each connector features solid pins that can handle more current than hollow-pin connectors.

Power Saving
The Power Saving function contains several settings to easily optimise power consumption and maximise energy savings. You can enable a CPU power limit, darken Aura lighting and set the fan profile to a Power Saving mode. You can also toggle the Power Saver plan that is built into Microsoft Windows.

Digi+ VRM Control
The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings.

AEMP III for Ultimate DDR5 Performance

ASUS Enhanced Memory Profile III (AEMP III) is an advanced firmware feature that empowers users to achieve unparalleled memory performance with cutting-edge CUDIMM memory. Through a two-phase comprehensive tuning process, AEMP III first optimises the clock driver and then the memory frequency. This results in the best balance between performance and stability, even at cutting-edge speeds of DDR5-7600 or higher.

DIMM Fit

DIMM Fit is an ASUS-exclusive BIOS feature that precisely analyses individual memory modules to optimise performance and pinpoint potential issues. This offers peak efficiency, compatibility, and system stability. Whether you are an overclocker seeking ultimate performance, a competitor pursuing the most responsive gameplay, or a content creator prioritising rock-solid stability, DIMM Fit provides optimisations tailored to your needs and your hardware configuration.

Two M.2 slots (up to 128Gbps)

The PRIME B860M-A offers a total of two M.2 slots, including one that supports data-transfer speeds of up to 128Gbps via PCIe 5.0, one that supports 64Gbps via PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives.

Cooler by Design

The PRIME B860M-A motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads.

4-Pin PWM/DC Fan
Each onboard header supports auto-detection of PWM or DC fans.

AIO Pump Header
A dedicated PWM/DC header supports self-contained water-cooling setups.

VRM Heatsinks and Thermal Pads
The massive VRM heatsinks and essential thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.

Multiple Temperature Sources
Each header can dynamically reference three thermal sensors. Fan Xpert 2+ lets you to map the temperature of supported ASUS graphics cards to optimise cooling for GPU- and CPU-intensive tasks.

M.2 Heatsink
One M.2 heatsink takes care of the M.2 slot, preventing throttling that can occur with M.2 storage during extended transfers.

Passive Chipset Heatsink
An aluminium passive chipset heatsink ensures optimal cooling and stable performance. It is more durable and longer-lasting than heatsinks with fans, which can be vulnerable to the build-up of dust and debris.

Smart protection
A dedicated integrated circuit protects each fan header from overheating and excess current.

ASUS Fan Xpert 2+
ASUS Fan Xpert 2+ software provides comprehensive control over fans. An Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.

Cooler compatibility
ASUS AIO coolers offer robust performance, high overclocking potential, bold aesthetics and customisable functionality for new motherboards, empowering you to build your dream gaming rig.

Empowering Connections

The PRIME B860M-A motherboard offers a versatile range of connectivity, including support for the latest version of PCI Express and an arsenal of USB ports which includes Type-C connections.

USB 20Gbps port
A batch of USB ports supports high-end rigs loaded with peripherals, including a rear USB Type-C port with transmission speeds of up to 20Gbps.

PCIe 5.0 slot
The latest processors introduce PCIe 5.0 support, doubling data transfer speeds compared to PCIe 4.0, enhancing signal integrity, and providing backward-compatible CEM connectors and support for previous PCIe versions.

Customisation and Personalisation

The PRIME B860M-A enhances the user experience across the board, from simplifying BIOS setting adjustments to offering customizable RGB lighting controls for a uniquely personal system aesthetic.

UEFI BIOS
The UEFI interface delivers easy-to-use configuration options for PC beginners, and advanced features for veterans.

ASUS DriverHub
Simplify driver management with automatic detection, one-click installation and update for smooth, efficient system performance.

Armoury Crate
Customise Aura Sync RGB and control ASUS devices. Includes product registration and updates.

Aura Sync
Complete RGB lighting control for enthusiast systems, ensuring seamless synchronisation with compatible hardware.

Addressable Gen2 RGB headers
Two Addressable Gen2 headers detect LED counts on compatible RGB devices, automatically adjusting lighting effects accordingly.

DIY Friendly

The PRIME B860M-A motherboard features EZ PC DIY innovations that simplify and speed up the PC building process, making DIY easy and convenient.

Pre-mounted I/O shield
Our pre-installed I/O shield safeguards ports, simplifies the build process, increases functionality and enhances aesthetics for PC DIY enthusiasts.

SafeSlot
PCIe 5.0 is twice as fast as PCIe 4.0. ASUS has adapted our SMT manufacturing for the faster SafeSlot, a reinforced metal sheath that ensures secure card installation and faster data speeds.

Q-LED Core
The Q-LED Core display produces colour-coded lights during the Power-On Self-Test (POST) that can help you troubleshoot potential issues.
